Description
Technical field
The invention belongs to forging equipment technical fields, specifically disclose a kind of cylinder body forging machine of hydraulic cylinder.
Background technique
Various machine components can be forged by forging equipment, compared to lathe plus more efficient, and are forged
Part out is to be integrally formed, high mechanical strength, long service life.
But in forging process, forging machine general structure used is complicated, part is more, manufacturing cost is high；Machine after forging
The residual skin of tool piece surface not can be removed, and influence part quality；Forging operation step is more, brings inconvenience to operator.
In view of the above-mentioned problems, the patent that notification number is CN101554639B discloses a kind of cylinder body forging machine of hydraulic cylinder, wrap
Include mainframe, mainframe top is equipped with pressurizing device, is equipped with inside mainframe and slides along mainframe and connect with pressurizing device
Forging apparatus, mainframe lower part are equipped with inner core lifting device, and the working plate of mainframe lower part is equipped with inner core stopping device.This
Invention can forge the cylinder blank of hydraulic cylinder for meeting actual demand and have higher forging production efficiency and economic benefit.This
Invention has many advantages, such as that construction is reasonable, easy to operate, labor intensity is low, at low cost, high yield rate.
When using above-mentioned patent formula, although reached construction is reasonable, easy to operate, labor intensity is low, it is at low cost, at
The high effect of product rate, but in forging process, impact force is excessive to be easy to appear block distortion, causes processing dimension inaccurate；Punching
Formed punch is easily damaged since impact force is excessive when pressure；And since impact force is big in punching course, the inertia of formation is big, is easy to make
Equipment shakes, and causes coupling part to be easy to appear loosening, security risk occurs.
Summary of the invention
The purpose of the present invention is providing a kind of cylinder body forging machine of hydraulic cylinder, occurs that impact force is excessive to lead to solve forging process
The problem for causing processing dimension inaccurate.
In order to achieve the above object, base case of the invention are as follows: a kind of cylinder body forging machine of hydraulic cylinder, including pedestal, institute
Pedestal one end is stated equipped with hydraulic telescopic machanism, the other end is equipped with guide rail, and the middle of the base is equipped with clamping device, described hydraulic to stretch
Contracting mechanism includes hydraulic oil container, oil pump and telescopic rod, and the oil pump is connect with hydraulic oil container, telescopic rod, is set on the telescopic rod
There is support rod, the support rod is equipped with crossbeam, and the crossbeam is equipped with support frame, and the crossbeam is slidably connected with guide rail, institute
Support frame is stated equipped with stepper motor, is successively arranged support plate and cutter head in the shaft of the stepper motor, the support plate and
Be connected through a screw thread between the shaft, be equipped with guide rod between the support plate and support frame, the support plate and cutter head it
Between set seamless steel pipe, for the seamless steel pipe sleeve in the shaft, the cutter head and clamping device are positioned opposite.
The working principle of this base case is: before forging to part, part being clamped with clamping device, starting step
Into motor and oil pump, since the shaft of stepper motor is equipped with cutter head, cutter head can drill to part；Operation of oil pump drives
Hydraulic telescopic machanism work, hydraulic mechanism, which is shunk, drives support rod to shrink, to drive crossbeam and stepper motor mobile to part；
It is to be threadedly coupled between support plate and shaft, shaft can make support plate dynamic to part when rotating, drive support plate and seamless steel pipe
It is mobile to part；Since seamless steel pipe sleeve is in the outside of stepping motor rotating shaft, seamless steel pipe also starts to part when cutter head drills
It is mobile, the redundance of hole inner wall is punched out；After the completion of punching, oil pump is adjusted, support rod drives motor to leave processing zero
Part, stepper motor reversion, drives support plate and seamless steel pipe to leave part.
The beneficial effect of this base case is: when using this programme forging parts, drill bit is first to drilling part, then device to hole
Wall is punched out, and the direct punching press avoided causes part deformation, ensure that the precision of processing part, easy to operate, user
Just.
Compared with prior art, drilled in this programme using stepper motor, cutter head rotate and reverse can to hole wall into
Row secondary operation, improves drilling efficiency；Part is punched out using seamless steel pipe, due to seamless steel pipe bending resistance torsional strength
Greatly, it is hardly damaged, long service life；Part is punched out again after drilling, reduces ram drag, at the same avoid use compared with
Big impact force is forged, and ensure that the integrality of part；Since impact force reduces, avoids and cause to rush since impact is excessive
Head damage；Telescopic rod is driven using oil pump when raising and lowering, it is not in larger inertia, energy that hydraulic oil, which transmits dynamical stability,
Guarantee equipment stable operation；Forging process first drills to be punched again, and entire mechanism is not susceptible to shake, and will not be caused by vibration and be drawn
It plays components to loosen, to bring security risk to operator.
Further, the cutter head and shaft are flexibly connected, and when needing to stamp various sizes of aperture, replace cutter head energy
Realize processing effect, while maintenance easy to disassemble.
Further, the seamless steel pipe internal wall is equipped with bar magnet, and the clast after drilling and punching can will be broken by magnet
Bits absorption band avoids influence of the clast to punching, is further ensured that the accurate of processing dimension in portalling.
Further, the seamless steel pipe reduces seamless steel pipe and zero close to the wedge shaped shape in the end of cutter head position, wedge shape
Part is punched the contact area in face, reduces punching resistance, goes on smoothly convenient for punching.
Further, the seamless steel pipe is flexibly connected with support plate, when needing to forge various sizes of hydraulic cylinder, is only needed
Seamless steel pipe will be replaced, can be achieved with forging effect, it is simple to operate.
Further, bearing is equipped between the crossbeam and guide rail, bearing element can reduce the friction between crossbeam and guide rail.
